Let it be simple and as direct as possible.
Interviewer : Tell me how much time (in days) and money would you require to clean all the glasses of each and every building (which is obviously composed of glasses) of New York City including all the glasses at the top as well as at the bottom of all buildings. Also mention the calculations for your contract and the money you would mostly prefer to accomplish this task. Most importantly you and only you have to do this job (i.e. you can’t ask anyone else to clean the glasses for you). You can even separately mention the costing of cleaning the window glasses and fixed glasses from both the sides (i.e. from inside as well as outside.)
* Time allotted for the question (to think and analyse) is half-an-hour.
** This was the most tricky, diplomatic and mind-manipulating question asked at one of the interviews conducted by Google for a highly paid job.

A farmer is taking her eggs to the market in a cart, but she hits a pothole, which knocks over all the containers of eggs. Though she is unhurt, every egg is broken.
So she goes to her insurance agent, who asks her how many eggs she had. She says she doesn’t know, but she remembers something from various ways she tried packing the eggs.When she put the eggs in groups of two, three, four, five, and six there was one egg left over, but when she put them in groups of seven they ended up in complete groups with no eggs left over.
What can the farmer and agent figure out from this information about the number of eggs she had ?
Is there more than one answer ?
PS:- Though I know the answer but still I want the answer in the simplest understandable manner possible. Thanks for all answers in advance.
